The two grew up in Massachusetts and played volleyball at GMU together. Patrick had transfered to GMU last year.

"From an international standpoint, he had the qualities to be a world-class athelete," GMU men's volleyball coach Fred Chao said. "He was 6'8", 230 pounds, huge leaping ability and a work ethic that would get him the skills he would need to compete at the highest international level."

Eight people on board the train were transferred to another train to continue their journey. Officials have not yet said why Sibley was on the tracks.

Counseling services are being offered to GMU students, staff and athletes.
